Therefore, the planned navigation route is suitable for the user to walk, and the safety of walking travel of the user can be ensured.
In this embodiment, each navigation route further includes characteristic information of the walking facility. The characteristic information indicates information on the number, type, trafficability, and the like of the walking facilities included in the navigation route.
Fig. 4 is a schematic diagram of an interactive interface provided in an embodiment of the present application. As shown in fig. 4, in this interface, after the user selects the "walking" travel mode and inputs the start point position and the end point position, two candidate navigation routes are determined in the map. Both candidate navigation routes include a walking facility.

In some possible implementations, the terminal device guides the walking direction of the user at some diverging intersections or turning points according to the target navigation route. For example, when the user needs to turn right, the terminal device prompts the user to "please turn right at the front intersection". For another example, when the user needs to cross a road, the terminal device prompts the user to "please walk across the road through the overpass".
The walking navigation method provided by the embodiment comprises the following steps: obtaining a walking navigation request input by a user in an interactive interface, wherein the walking navigation request comprises: the navigation method comprises the steps that a starting point position and an end point position are determined, at least one candidate navigation route from the starting point position to the end point position is determined in a map, and each candidate navigation route comprises walking facilities and characteristic information of the walking facilities; and responding to a target navigation route selected by a user from the candidate navigation routes and triggering a navigation starting request aiming at the target navigation route, and performing navigation prompt according to the target navigation route. In the process, the candidate navigation route comprises the walking facilities, so that the candidate navigation route is suitable for the user to walk, the user walks according to the candidate navigation route, and the safety of walking travel can be improved. Furthermore, the candidate navigation route comprises the characteristic information of the walking facility, so that the user can select the target navigation route according with the walking habit according to the characteristic information of the walking facility, and the personalized requirements of the user can be met on the premise of improving the travel safety.

And if the terminal equipment deviates from the special pedestrian facility, outputting first prompt information for prompting the user to pass through the special pedestrian facility. And if the distance between the terminal equipment and the pedestrian forbidden facility is smaller than a preset value, outputting second prompt information for prompting a user to forbid the pedestrian forbidden facility. Several possible examples are given below.
As an example, fig. 5 is a schematic diagram of another interactive interface provided in the embodiment of the present application. As shown in fig. 5, if it is detected that the user does not walk on the sidewalk or the walking track of the user deviates from the sidewalk by the terminal device according to the positioning information of the terminal device during the walking process of the user, a prompt message "please walk along the sidewalk" is displayed in the interactive interface to remind the user to walk through the sidewalk, so as to ensure the safety of the user when walking.
In another example, assuming that the terminal device detects that the user walks in the motor vehicle lane according to the positioning information of the terminal device during walking, a prompt message "please do not walk in the motor vehicle lane and please walk the pedestrian road" is displayed in the interactive interface, so as to ensure that the user walks in the safe area.
In another example, if the terminal device detects that the user gradually approaches the fence according to the positioning information of the terminal device during walking of the user, a prompt message "please do not cross the fence" is displayed in the interactive interface, so that the safety of walking and traveling of the user is ensured.
Optionally, in each of the above examples, the terminal device may further output the prompt information in a voice form. Therefore, even if the user does not check the display screen of the terminal equipment, the prompt message can be received and heard so as to adjust the user to walk in a safe area in time and ensure the walking safety of the user. In addition, the display screen of the terminal equipment is prevented from being frequently checked by the user in the walking process, so that the walking safety of the user is further ensured.
In some possible scenarios, the terminal device supports live-action navigation. Under the condition that a user adopts live-action navigation, a camera of the terminal equipment can be used for acquiring a live-action road image of a road in real time, marking facilities special for pedestrians and/or facilities forbidden for pedestrians in the live-action road image, and displaying the marked live-action road image on an interactive interface.

And according to the semantic information, marking special facilities for the pedestrians in the live-action road image, and/or marking forbidden facilities for the pedestrians in the live-action road image. And displaying the marked live-action road image in an interactive interface of the terminal equipment. Therefore, the user can intuitively know which walking facility the user should pass through and not which walking facility the user should pass through according to the marked area displayed in the interactive interface, and the navigation experience of the user is improved.
Optionally, the pedestrian-specific facility and the pedestrian forbidden facility can adopt different labeling modes so as to be visually distinguished by a user. It should be understood that the pedestrian-specific and pedestrian-disabled facilities can be labeled in a variety of ways, such as by color, for example, the sidewalk is labeled green, the fence or flower bed is labeled red, etc. The labeling can also be performed by lines of different forms. Of course, other labeling methods may also be adopted, and this embodiment does not limit this.
Fig. 6 is a schematic diagram of another interactive interface provided in the embodiment of the present application. Fig. 6 illustrates a scenario in which live-action navigation is employed. In the scene, in the walking process of a user, a camera of the terminal equipment acquires real-scene road images in real time. In the interactive interface of the terminal equipment, the live-action road image collected by the camera is displayed, so that the terminal equipment can perform navigation prompt based on the live-action road image to improve the navigation intuitiveness.
Referring to fig. 6, assuming that the terminal device detects that the user is currently located in the flower bed and a fence exists in front of the user, the terminal device may display a prompt message "please walk the sidewalk without crossing the fence" in the interactive interface to remind the user to walk in a safe area. With continued reference to fig. 6, the sidewalk area is marked in the live-action road image displayed on the interactive interface, for example, the sidewalk area is marked with a black border in fig. 6, and the black border is filled with an oblique line, so that the user can more visually see the sidewalk area in the interactive interface. It should be understood that the manner of marking the sidewalk in fig. 6 is only an example, and the present embodiment does not limit this. Optionally, the flower bed, fence, etc. area in fig. 6 may be labeled (not shown in fig. 6) so that the user can intuitively know which facilities are disabled.

For example, the walking facility information corresponding to each link is collected to obtain walking facilities included in the planned route. Further, characteristic information of the walking facility may be determined from the walking facility included in the planned route.
Further, according to the characteristic information of the walking facilities included in the planned route, a safety index corresponding to the planned route can be determined. The safety index indicates the safety of the user when walking through the planned route. For example, if sidewalks are arranged from the starting position to the ending position in a planned path, the safety of the planned path is high. If no sidewalk is arranged from the starting position to the end position in a planned path or only a single road section is provided with the sidewalk, the safety of the planned path is low.
Optionally, the server side is provided with a database, and the database stores the positions and types of the walking facilities set on different road sections of the road, that is, which type of walking facility is set at which position of each road section. In this way, the terminal device can acquire walking facility information corresponding to each link from the server.
Wherein, the walking facility information corresponding to each road segment stored by the service side may be obtained based on the historical road image of the road segment. For example, each road segment may be collected by a collection vehicle to obtain a historical road image.

As shown in fig. 8, the semantic segmentation model is used to perform semantic segmentation on the historical road image to obtain at least one region. The semantic segmentation model can be any one of the following: fcn, unet, segnet, deeplab, pspnet, etc. Each pixel in the image after semantic segmentation corresponds to a semantic label. And clustering and merging the pixels with the same semantic label to form a region. Optionally, the maximum external rectangle, that is, the connected domain, can be taken from the combined region, and the connected domain is reasonably expanded, so that the integrity of the object in the region can be ensured.
Furthermore, according to the position of each area in the historical road image and the semantic information corresponding to each area, the walking facility information corresponding to the road section can be determined. Specifically, referring to fig. 8, for each region, it is identified whether the object in the region is a walking facility and what type of walking setting is, based on semantic information of pixels in the region. In the case where the object in the area is identified as the walking facility, the setting position of the walking facility in the link may be determined based on the position of the area in the entire history road image.
Optionally, it may be further identified that the object in the area belongs to a pedestrian-specific facility or a pedestrian-disabled facility. If the pedestrian special facility belongs to the pedestrian special facility, the pedestrian in the area is determined to be passable, and if the pedestrian special facility belongs to the pedestrian forbidden facility (such as a fence, a flower bed and the like), the pedestrian in the area is determined to be impassable.
Through the image segmentation and identification processes, the walking facility information corresponding to the road section can be determined, namely, which walking facilities are arranged at which positions in the road section, and how the walking facilities are in traffic.
S704: and determining the candidate navigation routes from the plurality of planned routes according to the safety index, and displaying the candidate navigation routes in the map.
For example, a planned route with a safety index greater than a preset threshold may be selected from the plurality of planned routes as a candidate navigation route. Alternatively, several planned routes with the highest safety index may be selected from the plurality of planned routes as candidate navigation routes. In this way, the safety of the candidate navigation route recommended to the user is ensured.
In some possible implementation manners, a convenience index corresponding to each planned route is respectively obtained; the convenience index is used to indicate at least one of: time consumption information, distance information, energy consumption information and intersection number information; and determining the candidate navigation routes from the plurality of planning routes according to the safety index and the convenience index.
